Help to Buy Partial Repayment (Staircasing) — How to Buy Back a Tranche

Help to Buy Partial Repayment — What Staircasing Means for You

If you want to reduce the government's stake in your home without selling or clearing the entire equity loan, you can make a partial repayment — a process sometimes called staircasing. This allows you to buy back a percentage of your home in tranches, reducing both your ongoing management fees and the amount you will owe when you eventually sell or fully redeem the loan.

What Is the Minimum Partial Repayment?

The minimum partial repayment is **10% of your property's current market value** at the time of repayment. This is not 10% of your original equity loan, and it is not 10% of your original purchase price. It is 10% of what your home is worth when you make the repayment.

**Example:** Your home is now worth £320,000. The minimum partial repayment you can make is 10% × £320,000 = **£32,000**.

If your original equity loan was 20% of £200,000 = £40,000, and your home is now worth £320,000, the loan now represents £64,000 in real terms. A £32,000 partial repayment would reduce the loan percentage from 20% to approximately 10%.

Why Is the Minimum 10% of Current Value?

The structure is designed to ensure repayments are meaningful and to manage the administrative overhead of each transaction. Each partial repayment requires a RICS valuation, legal work, and a Land Registry update — the 10% minimum threshold reflects those costs and ensures each transaction delivers a proportionate benefit.

Step-by-Step: How to Make a Partial Repayment

**1. Commission a RICS valuation.** A RICS-registered surveyor must visit your property and produce a formal Red Book valuation. This must be no older than three months when you submit your application. Budget £250–£500 for this step.

**2. Apply to Target HCA.** Log in to your Target HCA account and submit a partial repayment request, attaching your RICS valuation. Target HCA will confirm the repayment amount and send you a redemption pack.

**3. Instruct a solicitor.** You will need a conveyancing solicitor to handle the legal side. They will liaise with Target HCA, receive the redemption statement, and process the payment. The Land Registry charge will be updated to reflect your new, lower equity loan percentage.

**4. Make the payment.** On the agreed date, your solicitor transfers the funds to Target HCA. You will receive confirmation that your equity loan percentage has been reduced.

**5. Confirm the updated charge.** Your solicitor will confirm the updated entry at HM Land Registry. You should retain a copy of the updated charge for your records.

Impact on Your Management Fee

After a partial repayment, your management fee is recalculated. Because the fee is based on your **original equity loan amount**, Target HCA will reduce the fee proportionally to reflect your new, lower loan percentage. For example, if you repay half your original loan, your management fee will halve.

How Often Can You Make Partial Repayments?

There is no fixed limit on the number of partial repayments you can make, but each requires a new RICS valuation and a new legal instruction. In practice, the costs of each transaction mean that repaying in larger tranches (when you have accumulated sufficient funds) is more economical than making frequent small payments.
